### Constructing a Cast Cylinder

You can construct a cylinder by changing any given feature into a cylinder. PC-DMIS constructs the cylinder at the centroid of the input feature. If a sheet metal point is used, the diameter is the probe diameter. For some sheet metal features (such as slots and notches) the width will be used as the diameter. For features that do not have diameters (lines, points, etc.), a value that is four times the probe diameter is used.

You can change the size of the cylinder; this changes the cylinder from DEPENDENT to INDEPENDENT. This means that when the cylinder is executed that the length and diameter will not change based on the input feature but will be independent of the input feature, while the position and vector will remain dependent on the input feature. This allows you to have control over the cylinder size in cases where the input feature doesn’t really have a length and diameter, such as a point. The DEPENDENT/INDEPENDENT field is a toggle field that you may change.

PC-DMIS uses the new attributes for all calculations (for example, if the diameter is changed) instead of the default values as described above.

To construct a Cast Cylinder:

1. Access the Construct Cylinder dialog box (Insert | Feature | Constructed | Cylinder).

2. Select the Cast option.

3. Select one feature. The feature can be of any type.

4. Click the Create button.

The Edit window command line for this option would read:
